Oxygen goes from the lungs to the tissues via the blood stream and CO2 goes back to the lungs via the blood stream
I think you mean picked up. It is the lungs.
Deoxygenated blood is not collected anywhere. Blood is a constantly moving stream - it never stops, as the question implies. The oxygen poor blood goes to the lungs, where it turns oxygenated as it takes up oxygen.
normally the oxygen transfer from the lungs to the cells through haemoglobin in most of the animals. the oxygen transfer occurs in lungs from the atmospheric air.
The lungs, as blood passes through the lungs, they deposit carbon and receive oxygen.
Breathed into your lungs from your mouth where it is absorbed into your blood stream, which is pumped up to your brain and around your body by the heart.
The lungs, I the alviolies.
Oxygen enters the blood stream through the air sacs in you lungs.
Oxygen goes from the lungs to the tissues via the blood stream and CO2 goes back to the lungs via the blood stream
No it is not connected directly but you are getting oxigen that travels in blood stream from your lungs to brain.
oxygen makes it redI would think it has to do with the amount of oxygen in the blood stream.
your lungs
The Lungs, Blood Stream.
The heart and lungs. Needs lungs for the oxygen. And the heart to pump the oxygen into the blood, to the brain
In air breathing animals, oxygen enters the blood stream through the alveoli, tiny sacs in the lungs. In water breathing animals oxygen enters the blood stream through the gills.
Oxygen is brought into the blood stream by inhalation. Carbon dioxide moves out of the cells, into the blood, and taken to the lungs to be exhaled. Oxygen in, carbon dioxide out.
The heart and lungs are so close together because the lungs have oxygen that are pumped into the heart so it can go into the blood stream. The lungs don't have blood but they transmit oxygen to the heart for the blood stream.
